Block Non-Educational Videos With YouTube Video Blocker
When installed, this extension blocks videos not in the Education, Science & Technology, or Howto & Style categories so you can focus on watching educational videos.
To do so, it first has to make sure that the YouTube site you want to block is still accessible by connecting to the Internet.
The application will not block YouTube.com (which is a Google-owned website), or YouTube's official mobile app.
To install the application, you will first need to create an account with Google. You will be redirected to Google to create your own key and then the app will work.
